• If you are trying to use Boolean operators, they must be ALL CAPS: zhang tian gan li hua ((((zhong john) OR (wrong john))) OR (wong john)) bonn iii ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang tian gan li hua ((((zhong john) OR (wrong john))) or (wong john)) bonn iii ;*".
